Hello,
I am trying to make a field that gives unique sample ID's if plant samples are indeed collected by individual collectors/surveyors. Something like {Year}{created_user}{last number +1} would be terrific. But even a plain old autoincrementing integer would be better than nothing. Is this possible? I am using ArcGIS 10.2.2, ArcGIS online, and version 10.3 of the iOS Collector app. Thanks!
